当我使用Spring和Hibernate时，我遇到了这样的错误：

21:07:00,347 ERROR TaskUtils$LoggingErrorHandler:95 - Unexpected error occurred in scheduled task.

但我不知道我的代码中导致此错误的确切行。我该怎么找到它？哪个文件是“...... 22更多”登录？

实际上，代码是fastfds-monitor，我是从互联网上下载然后反编译的。有人用过吗？

最后我明白了为什么会这样。当我将数据设置为与mysql表连接的对象时。当我这样做时，I set an primary key to the object.所以当它传递给hibernate时，hibernate发现对象的主键已经设置好，所以它运行update方法，而mysql中没有行有这个主键，因此更新失败，并且发生了此错误。
